My sabayon is 4.1 kde x86_64.I just upgraded to rev 1028, qt packages was updated to 4.5.1.kdm version is 4.2.2-r2.

After that i restart, but kdm was not displayed.From kdm.log, it display error message something like "kcrash:kdmgreeting crashed, due to incompatible qt library"

EDITED:I just did another world upgrade, then it fetched qt-gui,qt-svg and qt-assistant.Strange, my previous world upgrade change my revision to 1028. It seem above qt packages were not installed.Also my ktorrent upgraded to latest revision, but equo doesnot updated to 0.90.

During installation of skype, Equo updated as dependences qt to 4.5 version and asked to replace conf file of cups... I said ok.All installed successfully but when I restarted sabayon,it's stacks in console mode instead of going to KDM.When qt packages installed in console i saw something like "After update of qt KDE widgets and applications might not work.You need to recompile kde "How to recompile kde or may be it can be solved in other way?
